Implementing Integrating the HealthCare Environment (IHE) using the Business Process Execution Language

Abstract

The management of diverse information has gained utmost importance in the healthcare community. The biggest hurdle in passing the information seamlessly across the enterprise is the lack of integration and interoperability. Integrating the Healthcare Environment IHE is a framework to achieve interoperability in an Intranet based environment. The thesis has proposed a method to build integrated medical application for the execution of internet based IHE workflows. As Interoperability and Health information exchange is more inclined towards the business concept instead of being technical. Hence another goal is to provide application integration using business process in Service Oriented (SOA) Environment. In Proposed methodology, the IHE Laboratory workflows are mapped as Business process in the real world scenarios using Business Process Executable language (BPEL). For this purpose, the contents of IHE Lab TF are structured and the requirements of medical e-services are defined. An open source API HAPI is used for generating and building HL7 messages. Various fields in HL7 message segments are extracted and manipulated to create WSDL, BPEL and XML files for initiating business process. The business process interoperates with web services of IHE actors and represents IHE workflows. The major achievement of proposed framework is the alignment of IHE workflows with BPEL process and interoperability in healthcare across internet. The implementation of IHE system in terms of business process will help to achieve the true practical interoperability in the field of Healthcare
